Demographics of Company Ownership
Please note that the information available is contingent on disclosure. For Canada, currently there is no source available that allows you to search for company lists by specific demographic criteria.
Also included below are self-reporting directories for specific demographic groups. These are maintained by external groups and updates may be sporadic, and they may not be comprehensive because they rely on self-reporting.
Outside of Canada, check the country's census data, statistics sources, or industry/economic ministries for data.
